Read command

The read command reads the supported modem system modes.

Response syntax:

%XSYSTEMMODE: <LTE_M_support>,<NB_IoT_support>,<GNSS_support>,<LTE_preference>

The read response parameters and their defined values are the following:

<LTE_M_support>
0 – LTE-M not supported
1 – LTE-M supported
<NB_IoT_support>
0 – Narrowband Internet of Things (NB-IoT) not supported
1 – NB-IoT supported
<GNSS_support>
0 – Global Navigation Satellite System (GNSS) not supported
1 – GNSS supported
<LTE_preference>
0 – No preference. Initial system selection is based on history data and Universal Subscriber Identity Module (USIM).v1.1.xv1.2.xv1.3.x
1 – LTE-M preferred.v1.3.x
2 – NB-IoT preferred.v1.3.x
3 – Network selection priorities override system priority, but if the same network or equal priority networks are found, LTE-M is preferred.v1.3.x
4 – Network selection priorities override system priority, but if the same network or equal priority networks are found, NB-IoT is preferred.v1.3.x

The following command example reads the supported system mode:

AT%XSYSTEMMODE?
%XSYSTEMMODE: 1,0,0,0
